MI-Poser

Inside-out tracking of human body poses using wearable sensors holds significant potential for AR/VR applications, such as remote communication through 3D avatars with expressive language. Current inside-out systems often rely on vision-based methods utilizing handheld controllers or incorporating densely distributed body-worn IMU sensors. The former limits hands-free and occlusion-robust interactions, while the latter is plagued by inadequate accuracy jittering. We introduce a novel system, MI-Poser, which employs AR glasses two wrist-worn electromagnetic field (EMF) to achieve high-fidelity upper-body pose estimation mitigating metal interference. Our lightweight system demonstrates minimal error (6.6 cm mean joint position error) real-world data collected from 10 participants. It remains robust against various movements operates efficiently at 60 Hz. Furthermore, an sensor co-located EMF sensor, MI-Poser presents solutions counteract effects interference, inherently disrupts signal during tracking. evaluation effectively showcases successful detection correction interference our EMF-IMU fusion approach across environments diverse profiles. Ultimately, offers practical particularly suited body-centric applications.
